### 4.1 Quick start
|
||||
|
||||
PP-Structure currently provides table recognition models in both Chinese and English. For the model link, see [models_list](../docs/models_list.md). The following takes the Chinese table recognition model as an example to introduce how to recognize a table.
|
||||
|
||||
Use the following commands to quickly complete the identification of a table.

After the operation is completed, the excel table of each image will be saved to the directory specified by the output field, and an html file will be produced in the directory to visually view the cell coordinates and the recognized table.
|
||||
|
||||
### 4.2 Train
|
||||
**NOTE**
|
||||
1. If you want to use the English table recognition model, you need to download the English text detection and recognition model and the English table recognition model in [models_list](../docs/models_list_en.md), and replace `table_structure_dict_ch.txt` with `table_structure_dict.txt`.
|
||||
2. To use the TableRec-RARE model, you need to replace `table_structure_dict_ch.txt` with `table_structure_dict.txt`, and add parameter `--merge_no_span_structure=False`
|
||||
|
||||
### 4.2 Training, Evaluation and Inference
|
||||
|
||||
The training, evaluation and inference process of the text detection model can be referred to [detection](../../doc/doc_en/detection_en.md)

### 4.2 训练
|
||||
**NOTE**
|
||||
1. 如果想使用英文模型，需要在 [models_list](../docs/models_list.md) 中下载英文文字检测识别模型和英文表格识别模型，同时替换`table_structure_dict_ch.txt`为`table_structure_dict.txt`即可。
|
